Application filed April 12,

3.911. Serial No. 620,647,

To all whom it concern:

Be it known that We, ISRAEL German and SAMUEL Gnrinm each a subject of the Czar. Russia. and each a resident of lileriden, in the county of New Haven and State of Connecticut, have invented a new and 1111- proved Percolator, of which the following is n specification.

lur invention relates to that. class of devices employed for preparing coffee and like beverages and especially to that class in which a liquid, as WitQI, is supplied to and percolates through the coffee or like material from which the bei' 'erage is being iadc, and the object of our invention,

-,aii'ioii; others, is to provide a device of this class that will begin to operate in a minimum length of time, and one in which the supply of liquid to the coffee or other material may be regulated to produce the moss eiticient results. 1

Qther objectsito be derived from our lin proved apparatus will appear from the accompanying description taken in connection with the accompanying drawings, in. which The figure 1s it NOW in elevation of an contents may beobtnined from the vessel.

A base (3 serves as siu iport for the urn or vessel and fountain tube 7 projects upward through the chamber 8 int-he urn to the interior of a basket 9 supported at the upper part of the urn, and having a cover 10. The location and arrangement of the upper end of the tube 7 in the basket or holder 9 may be the same as in many of the constructions oi devices of this class nt the present time, theupper end of the tube being located at some distance above the perforated bottom or" the basket or holder 9, the liquid is ejected from the mouth of tilt) tube it will fall over the codes materiel held by the basket necessary herein, and especially as it forms no part of our present invention.

An opening 11 extends through the bot tom of the urn into the space inclosed by the base 6 and a bushing 12 is located in this opening, this bushing ha a lip l3 resting against the bottom or the chamber in the urn and a screw threaded outer end ill. A. heating plate 15 has a recess extending from its upper end into thobody of the plate, the mouth of this recess being threaded to fit the threaded end of the bushing 12 and the lower part of the recess forming a heating;- chamber 16. The parts are thus held in engagement, the. plate 15 being screwed upon the bushing until its upper edge abuts against the inner surface of the upper part of the inclosure in the base 6, the bushii'ig 12 being thus tightly drawn to place and the parts being thus firmly secured, Any additional means for packing the joint may be employed it such shall be desired. The plate 15 has a flange 17 common to devices of this kind a means of increasing the heating surface.

The opening" tlu'ough the bushing is proferably tapered from a larger dimension at the top to a smaller dimension at the bottom and in this openino' a fountain 18 is located, the lower end oi inc IliOlHll'fllH {TITOjCClTlNQ some distance below the end of the bushing, thus forming the chamber 16 into an annular inclosure at its upper end to contain heated elements to heat the-projecting end of the fountain and the liquid as it flows therethrou gh. tain has a recess extendingupward constituting a valve chamber 19 and a. valve recess 20 opens upwardly from this valve chamber with a port-Q1 leading into and commui'iicating With the fountain tube .7. lnlets 22 extend from the upper side of the fountain into the valve chamber 19, V 1lVG rods 23 extending through these inlets and supporting inlet valves 2& at their upper ends, these inlet valves controllingthe inlet flow of fluid to the valve chamber 19. An, outlet valve is located in the talve cl' an'iber 19, this outlet Valve including a base a a dome 26 rising therefrom and elite vinto the valve recess 20, conning 1 The lower end of the foun ing' from the space within. the dome into the valve recess. A valve ring 28 lits lhe screw threaded all of the valve ohamber 19, lie is ring having a central. opening and polls through lhe latter of which. the

liquid may flow into-the hearing chamber 16.

The base-25' of lhe outlet valve rests upon this ring-and by adjusting the position of the ring the location of the 1nlet valves 2% with'respect-to theopenings 22 may be denterininedslso that these valves may completely close lheopenlngs at CGZlZlHl lIlDGS "if des1red,' or a certain, amount of liquid may be, permitted lo continually flow.

ispacezvvihhin the dome being directly over the opening' ll through the ring 28 and the dome 'thus directing the flow of fluid from Said heating chamber and through {the recess 201 'llheiaclaon of the outlet valve is extremely SBHSlllVG and its operation to conirol the delivery of fluid to the tube 7 also actual'csihevalves Q11 and thereby provides 'a'nieasured' supply: to lhe heating chamber 16. The dome also prevents any ofthe heel;- ed l quid which has started on its way to the tube 7 from mixing withioolder liquid, which ,mighi; oiherwisebccur in the initial, movefi'nenl' of rho valve, which mixing of th 1 uid's is undesirable v 1 Wh le We have shown rind described here.-
